Armin Alazim

Armin is a character in MPST and served as the main antagonist in season 1 and first half of season 2, and then served as a tritagonist in the third season of Zero Tolerance. He's known as a very stubborn kid that ms. Kyle had a hard time with, to the point she had to hurt him to save Andrew.

Personality
He is known to have a hard head, to the point he will cause a lot of violence or major (and unwanted) debates with other students such as Andrew himself.

He's also known for his huge ego, where him having a trainer in the basketball team made him go away from the team, leaving it unknown to whether he had entered another team or entirely withdrawn.

Ironically, when he heard the person he hated got into an accident, he got angry instead of being happy because of how much he wanted to beat him so bad.

And that temper once caused him to make a mess towards not only him, but also the others in the forest (Kevin, Nate, ms. Kyle, Josh and Nate's mother), as he once threw a rock towards a monkey, and when the other monkey witnessed it, it gathered reinforcement to hunt Armin down. It's unknown if he had learn this lesson ever since the incident, as their fates were unknown between the ending of Zero Tolerance: The Hunting and Sporty Crime Part 2.

But he's not all that bad - when he saw Nate passing out due to the arrow in his shoulder, he was worried with what would have happened to him next, and might have been possible that he helped the others to carry him to the hospital. Long story short, he still had concern for others' well-being.
